Performance Engine Cooling

High Capacity Radiators, Electric Fans, Silicone & Braided Hoses, High Output Water Pumps

If your car’s cooling system fails, your car will grind to a halt by the side of the road in short order. Two-thirds of the energy in a gallon of gasoline turns to heat inside your engine, and it’s the responsibility of the cooling system to remove that heat promptly and efficiently. The entire cooling system is filled with a mixture of ethylene glycol and water, laced with additives to retard corrosion.

Cooling Systems

This coolant is pumped through passages in the cylinder block and heads by the water pump usually driven by a rubber belt. It then passes through the radiator to dump heat into the air passing through it. The customary 50-50 concentration of coolant has a boiling point above 212F. Cars have pressurized cooling systems - as high as 16psi - so the boiling point is as high as 300F. That same 50-50 concentration also won't freeze until -34F.

The water pump has two functions: first off, to pump coolant around the cooling system, and also, to keep that coolant on board. A seal surrounds the shaft that's spun by the fan belt, and coolant can seep around it. Surprise, it's more likely to leak when cold, and there is no pressure to keep the seal pressed against the shaft. There's a thermostat, often nearby the water pump, that short-circuits coolant to the radiator, which helps the engine warm up to normal operating temperature more rapidly.

The radiator is what does the heavy lifting in the cooling system. Hot coolant is pumped through fat rubber hoses into the end or top tank, where it flows through small tubes to the other end or bottom. The tubes are covered in fins, which heat up the air flowing through the radiator. A fan, powered by the belt that drives the water pump, forces air through the radiator. When the vehicle is moving, air flows through on its own, which is why many cars use electric fans that only run when the coolant is too hot, saving the energy the fan consumes.

Cooling Systems

The radiator cap has two functions: the first is to keep the system pressurized when the engine is hot. As the coolant heats up, it expands, and a small amount will be vented. The cap routes this through a hose to the overflow tank instead of dumping it on the pavement. When the engine cools, a one-way valve in the cap allows coolant from the tank back into the radiator, keeping the tank 100% full. A bad cap can allow coolant to vent at too low a pressure, allowing the coolant to boil at too low a temperature, or not allow it to return when the engine is cold, keeping the system chronically underfilled.

"Antifreeze" is a chemical, primarily consisting of ethylene glycol, which when mixed with water serves to lower the freezing point and raise the boiling point of the mixture. Traditionally, the combination of antifreeze and water is known as "coolant". As opposed to air-cooled vehicles which rely on fan-driven air blowing over engine components, water-cooled...
Everyone knows that your vehicle's engine needs its oil and filter changed at regular intervals. Most folks also know that there are other items which need regular servicing and replacement, such as the air and fuel filters. But what about the cooling system? The fact is, a modern vehicle's cooling system does such a great job at preventing an engine from...

CARiD are very professional. I purchased the wrong Mishimoto radiator and I contact them if I can exchange it for the right one. They are the best! I got my new radiator in a fast time and got my money back from the wrong one. I can say that this place is well maintained and I don't want to purchase any other parts other then from here. Great job you guys! Easy to install! Great quality too! **DOUBLE thumbs up!**
